COMBINATION HEATER roa PERMANENT wAvmo Application filed October 18, 1927. Serial No. 226,862.

This invention relates to an improved tubular heater or treating device particularly adapted for use in connection with the practice of permanent hair-waving methods.

It is an object of the invention to provide a device of this character by means of which those portions of the hair adjacent the scalp may be efliciently treated.

It is a further object to provide a device of this character by which'the treatment may be confined to those portions of the hair which are adjacent the roots, or by which, at the option of the operator, the entire hair strand may be efliciently treated.

Another object is that of furnishing a heater or treating device, the individual parts of which will be of simple and light construction and capable of ready assemblage, aside from the fact that the completed unit will operate with maximum efficiency and freedom from mechanical difiiculties over long periods of time. 1

With these and further objects in mind, the invention accordingly comprises the features of construction, combination of elements and arrangement of parts Which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevational view of the clevice with the auxiliary tube ready to be inserted therein;

Fig. 2 is a vertical, longitudinal sectional view, partly broken away, showing the auxiliary tube partially in position;

Fig. 3 is a transverse sectional view taken along the line 33 of Fig. 2 and looking in the direction of the arrows; and

Fig. 4 is a similar sectional view taken along the line H in Fig. 1 and looking in the direction of the arrows.

It will be appreciated that in the permanent waving of human hair the following procedure is usually resorted to: A strand of hair is twisted and coiled around a spindle of any desired type, and a moist pad embodying treating chemicals is disposed around the coiled tress. The whole is positioned within a tube or similar receptacle, having a heating element associated with it, said heating element ordinarily taking the form of an electrical resistance suitably insulated from the tube body. Ordinarily, the end of the pad which is disposed around the hair extends from the end of the tube and adjacent the scalp of the person being treated, and at this point it is conventional to dispose a clip or confining member around the protruding pad end in order to prevent any vapors, which under the treatment of the hair will be generated within the tube, coming into contact with the scalp of the person being treated.

Under certain circumstances, however, it is found to be desirable to vary the heat treatment of the hair when waving, particularly in respect to heating certain portions thereof to agreater extent than other portions, for example, when the hair of the person being treated has been waved previously and has grown out, the wave remains to a certain extent in the old hair and it is necessary to subject only the newly-grown portions of the hair to heat treatment.

In the drawings, the numeral 10 designates a short-heater unit having a coil 11 surrounding an interior tube 12 and in turn surrounded by a cap 18. At its outer end the tube 12 carries a flange 14 providing a slightly flared seat 15, said flange comprising the closuremember between the tube 12 and the cap 13.

Associated with the cap in heat-conducting relation is a plurality of radiating-members 16, which, in the exemplification shown, comprise a series of rod-like members, certain of which, as 16, preferably are hollow, for a purpose hereinafter described. At their upper ends the members 16, 16 are held in spaced position, for example, by means of a suitable disk 17 of fiber or like material, through which they pass, and which serves as a handle by which the heater may be manipulated.

Imposed upon the disk 17 is a mating disk 18 of similar material, which is held adjacent the disk 18 by any suitable means, as, for example, by passing certain of the members 16 therethrough and rip-setting them thereon, as at 19. Suitably disposed with respect to the hollow members 16 and one of the members 16 are openings 20 in the disk 17. Through one of these openings a ground wire 21 is passed which is attached to one of the said members 16 and serves to ground the entire frame construction. Through the other openings are passed the wires through which current is supplied to the heating element '11,- such wires passing downwardly to the heating element through the hollow members 16".

It will thus be seen that the device above described provides a short tubular heating element whieh is light in construction and which is particularly adapted efiiciently to wave the hair near the scalp. I-Ioweveuzin order that the device also may be adapted to treat a longer length of hair than that near the scalp, it is provided with an auxiliary tubular member 22 which is adapted to be passed through the rings 17 and 18 until it seatsin the member 15, whereby the heat from the element 10 and any vapors which may hzwe evolved during such heat treatment will,

be carried upwardly around the hair, so that the hair is treated up to its end portions: in substantially uniformly decreasing amounts, In other words, that portion of the tubenea'rest the heater unit is hotter than portions fur ther removed.

In order that the interior bore of the assembled device may be smooth, the auxiliary tube 22 preferably is substantially of the same diameter as that of the tube 12, hence the flaring of the seat 15. To aid in retaining the auxiliary tube 2 in position, the ring 18 preferably is provided with resilient means for engaging the auxiliary tube, and in the exemplification shown such means comprise spring-pressed ball elements 23, which protrude slightly through openings 24 m the member 18 and engage the auxiliary tube 22 to the rearward of the head 25. It is to be understood, of course, that any suitable construction of retaining elements may be used without departing from the spirit of the invention. The auxiliary tube 22 also may be provided at its upper end with a suitable handle member, which, in the exemplification shown, comprises a fiber disk 26. c

When the device is used for waving only that portion of the hair near the scalp, a short type of pad preferably should be used, and a pad particularlysuited for this purpose is exemplified in my copending application, Serial No. 227,404, filed October 20, 1927, in which provision is made for the escape of eX- cess gases, vapors, steam or heat from those portions of the hair which are not situated within the heater unit proper.

WVhen longer portions of the hair are to be treated, and the auxiliary tube 22 is used, a longer type of pad preferably should be used,

such as is shown, for example, in United States Letters Patent to Ernest O. F rederics, No. 1,596,247,issued August 17, 1926.

Since certain chan es may be made in the above construction, and dif erent embodiments of the invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings" shall" be interpreted as illustrative and not in a limiting sense.

It is also to beunderstood that the following' claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
